Below is the MotoSport proprietary step-by-step guide for expert air filter cleaning and replacement, tailored for your specific ride.
Why Clean & Replace the Air Filter?
- Engine Protection – Dual-foam filters trap airborne dirt, sand, and dust, preventing abrasive particles from causing engine wear.

When to Service the Air Filter
- After every ride in dusty or sandy conditions
- Every 2–3 rides in average trail conditions
- Inspect before every ride for visible dirt or damage
Tools & Supplies Needed
- Clean, lint-free rags
- Mild filter cleaner (solvent-based or biodegradable)

- Gloves (recommended)
Step-by-Step Cleaning Guide
- Remove the seat: Release the seat latch and lift off the seat to access the airbox.
- Remove the air filter: Unclip the air filter cage and gently pull the filter from the airbox.
- Inspect the air filter: Check for tears, disintegration, or seams coming apart. Replace if damaged.
- Clean the filter:
- Submerge filter in cleaner and gently squeeze (do not twist or wring) until all old oil and debris are removed.
- Rinse thoroughly with clean water and repeat if necessary until the filter is clean.
- Gently press out excess water and allow the filter to air dry completely.
- Oil the filter: Once dry, apply air filter oil evenly, working it carefully into all areas of the foam. Do not over-oil; excess can impede airflow.
- Reinstall: Inspect the airbox for dirt & debris, then insert the filter onto the cage and fit it securely. Ensure the filter creates a tight seal to keep unfiltered air from bypassing.
- Replace the seat.
Pro Tips for the 2006 Husqvarna CR125HQ Owner
- This model's airbox can accumulate debris near the seal — always wipe down contact areas before reinstallation to prevent dust leaks.
- Use a filter skin or outerwear in extreme dust to extend service intervals and protect your main filter foam.
- Check the filter cage and mounting flange for any warping or cracks; replace if damaged for a secure fit.
When to Replace the Air Filter
- If foam is torn, seams are separating, or the filter stays stained after cleaning
- At least once per season for regular riders (more frequent for racers or in harsh conditions)
